The basic idea
Hormesis describes a pattern where a manageable stressor may trigger adaptive responses. Exercise is the clearest example; heat and cold exposure are often discussed through a similar lens.
The dose matters
Too little stress may not create adaptation, while too much can impair recovery. Research suggests context, timing, and individual tolerance matter.

Hormesis and physiological adaptation

The hormesis model is useful for understanding stress adaptation, but practical protocols must account for recovery capacity.
FAQ
Is hormesis always beneficial?
No. Hormesis depends on dose, timing, and recovery capacity. Excessive stress can be counterproductive.
